应用于Ad Hoc网络的时延敏感自适应路由协议

DSARP:Delay Sensitive Adaptive Route Protocol for Ad Hoc Network

针对Ad Hoc网络中实时业务对网络平均时延的要求,提出了一种应用于AdHoc网络的新型路由协议——时延敏感的自适应路由协议。该协议在保持“最少跳数”的最佳路由条件下,增加了“平均最短时延”的约束条件,从而不仅可以为实时业务(即时延敏感的业务)提供可靠的路由,同时还能根据网络节点当前的业务流量,动态地选择最佳路径,降低网络的平均时延。这是一种新型的有QoS保证的路由协议。仿真结果表明,该协议的确可以有效地改善网络的性能。

A novel routing protocol for Ad Hoc Network——DSARP (Delay Sensitive Adaptive Route Protocol)is presented, which not only provides reliable route for delay sensitive traffic, but also can select the route based on the constrained condition 'the shortest route and the smallest average delay' . Therefore, the DSARP is assure to provide QoS guarantee and improve the performance of the network. Simulation results show that DSARP outperforms DSR router protocol used in Ad Hoc wireless networks.
